Abstract: The invention relates to a method for producing a contoured filter element, according to which method at least one filtering medium is applied to a flat backing material and is detachably secured thereto. The filtering medium is cut out on the backing material to form the contoured filter element and said contoured filter element can be detached from the backing material for use. The invention also relates to a filter element arrangement produced by means of this method.

Abstract: The invention relates to a dressing arrangement and to a method for treating a wound of a human or animal body by means of vacuum. The dressing arrangement has an absorbent body for absorbing wound secretions, the absorbent body being designed for insertion in a cavity of the wound. Furthermore, a separating element is provided, which is arranged between the wound and the absorbent body. Furthermore, a cover element, which is designed to cover the wound, together with the absorbent body, in a substantially airtight manner, and a connecting means are provided, which connecting means is arranged for connecting a vacuum source to the cover element. According to the invention, it is provided that the separating element is designed to be larger than the wound to be treated, a protruding edge portion being formed, and that the edge portion is attached to a skin region at the edge of the wound.
